Specification of Letters Patent. Patented M 31 1g21 Application filedOctober 13, 1919. Serial No. 330,433.

To all whom it may concern:

Be it known that I, SooTT M. ABBOTT, a citizen of the United States,residing. at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAdjustable Bookmarks, of which the-following is a specification. I V

The object of this invention is to provide an improved book-mark, whichwill combine physical flexibility as well as flexibility, figurativelyspeaking, in its being so readily conformable to various types of booksand ways in which the same are used.

More specifically, the invention has for its object the provision of abook-markwhieh is particularly designed for and adapted to be used withthe Holy Bible, and such guides used in the study thereof as that workwhich is known as Christian Science cmd HcaZth used by ChristianScientists, wherein several correlated portions of the book are arrangedin such manner, or: that when read consecutively they form ,what mightbe termed a more or less complete exposition ofv a par- 1 Y ticularsubject.

A further object of the invention is to provide a book-mark comprisingmeans removably attached tothe opposite sides of the binding, yieldingmeans extending between the corresponding end portions of sald firstmeans, and removable elements yield ingly engaging and supported by saidyielding means and adapted to be positioned between the pages of a book,and sa1d lastnamed means being provided with flexlble arms hingedlyconnected thereto, and'prefen ably extending to the laterally outer edgeportion of the leaves of the book and supporting tabs, which may in turnbe provided with any desired numerals, letters, or the like. Y

With these andother objects in view, the

invention comprises details of construction and a method of operationhereinafter fully described when readin conjunction with theaccompanying drawings, inwhichFigure 1 is a perspective view of a book,wlth wh1ch is associated. the preferred embod ment of the invention;Fig. 2 is a perspect ve view of the-rear portion of a book so equipped;Fig. 3 is a side elevation of one of the ele ments adapted to-beattached to the sides of the book-cover; Fig. 4 is aplan view of one ofthe book-marking elements complete;

Fig. 5 is an enlarged detail perspective view of the free end portion ofone of theflexible marker-arms, showing the method of attachng thenumbered tabs thereto; and Fig. 6 1s a fragmentary plan'viewof one'endof a modified form of marker element.

Referring to the drawings, a book is shown as comprising oppositelypositioned side-boards 1 and 2,.connected at their rear portions by anintegral'back 3, while between said boards are positioned the usualleaves 4. 'An elongated stripe of suitable material, and being providedat its opposite ends with laterally and reversely curved portions 6, isadapted .to he slid longitudinally from the outer freeedge to therearmost porpo on of each of the binding boards 2 of the o'ok.

, These'strips are furthermore prov ded upon their looped portions withpins 7, surrounding which are revolubly mounte ed pulley-wheels 8, whilebetween the wheels,

located at each endiof the backing 3 of the book, a resilient i member,such' asa-small rubber-band 9, is extended.

When a given portion of the book is to be marked for: instantlyrelocating the same,

one of the markerunits, shown inFigs. .4:

and 5, is placedb'etween theleaves, which latter'upon separating exposesto the reader the portion in which he is interested. 7

These elements each comprise an elona gated flexible strip 10 of very.thin material,,provided in their lower end portion with an invertedU-shaped recess ll 'adapted to" receive and partially surround one ofthe side portions of the lower of the rub-1 ber-bands-9. .The-upperendportion of said member "is provided with an aperture 12,

which preferably has one lateral edge 18 diagonally positioned, saidlast-named aperture being adapted toreceive and partially surround oneside portion of the'up'per of the rubber-bands 9, and by the arrangementof the apertured edge portion 13 to resist purely accidental dislodgmentof the marker from between'the leaves of the book.

Each of the elements 10 is furthermore provided. ata predeterminedposition between its end portions. with anelongated aperture 14, throughwhich extends, and is.

reversely bent, one edge portionv 15 of a hinge member, which has itsopposite end portionprovided with spaced parallel extensions lG.adapteolto be bent laterally in the same direction'as'the portion 15,and reversely toward the same in order to cooperate with said otherportion, to rigidly grip the marker member. Furthermore, between thespaced cars 16, there extends a relatively fine pin 17, around which isslidably mounted a hinge member 18, to the free end portion of which issecured a preferably very thin flexible markenarm 19, which extendslaterally outwardly toward the free edge portions of the leaves of thebook when the marker as a whole is in normal operative position.

The faces of the outer end portion of each marker-arm 19 are covered bya folded sec tion of metal comprising oppositely posi: tioned sideportions 20 and 21. The side 21 is provided near its free end withoppositely positioned cu -out portions 22, and at its extreme end withlaterally outwardly extending arms 23, which are adapted to be bent inopposite directions and thence toward each other around the adjacentportion of the arm 19, while the side portion 20 of this folded memberis provided atits end portion with oppositely extending ears 24, whichare similarly bent in opposite directions and thence toward each othersurrounding the adjacent portion of the arm 19, andterminating in thecut-out portions 22, and with their outer exposed surfaces flush withthe corresponding surface of the side 21 of the saidmember. These tabsmay be positively secured in their desired position by means of smallrivets 25, or the like, passing through the tab and the arm 19, and itis to be noted that the marker-arms are hingedly positioned upon therespective sup porting members 10 of a series in such differentconsecutive positions as to make their progress numerically from one endtoward the other of the said members.

One or both of the sides 20 and 21 of the marker-arm or tab may beprovided with numerals, letters, or other suitable indicia, such forinstance as that illustrated, for the purpose of indicating the sequencewith which the portions of the reading-matter of a book are to belocated. Also it has been found greatly to the advantage of the user ofsuch a marker to provide the looped portions 6 of each of the members 5with bands 26 of any suitable material, which same 0pcrates to lessenthe chance of the members 5 accidentally shifting with respect to the 27having a restricted opening 28 in one side portion of said member,instead of in the end itself as is true with that form of the deviceshown in Fig. 4.

/Vhat l claim and desire to protect by Letters Patent of the UnitedStates is l.
